Just a little math:
48 drops = 1ml, it takes 12 drops to make a 10ml finished bottle of juice if mixing at the 2.5% range. at that mixing rate 1ml of concentrate can make 40ml of finished juice so one 7ml bottle of concentrate can make 280ml of finished juice!
I am not sure if you'll like it or not but chances are you will as most everyone who has tried them sure do and they meet your alcohol based needs.
$6.99 per Bottle for concentrate that makes that much juice is worth the risk with so many rave reviews and after mixing a 10ml tester (Only 12 drops) or 5ml tester at only 6 Drops if your not liking the flavor re-sale it here and I bet there will be takers. Win, Win
